UNITED STATES PATENT OFFICE.

GEORGE A. FULLERTON, OF BOSTON, MASSACHUSETTS.

HEEL-STI FFENER MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 384,753, dated June19, 1888.

Application filed July 23, 1886.

To all whmn it may concern:

Be it known that I, GEoEoE ARTHUR FUL LERTON, of Boston, in the countyof Suffolk and State of Massachusetts, have invented a new and usefulMolding-Machine for Making Heel-Stiffeners and Like Articles, of whichthe followiugisaspecitication, reference being had to the accompanyingdrawings, in which Figure l is a front elevation, and Fig. 2 a verticalsection on lines 2 2 of Figs. 1 and 4, of my machine. Fig. 3 is a sideview of my machine broken off, and Fig. at is a plan of my machine.

My invention consists of a former between two nippers so organized thata blank to be molded can be laid across the former and have its endsheld by the nippers and then be drawn over the former and shaped bybeing strained about the former.

In the drawings, A is the former. (Shown as rigidly mounted upon theframe a of the machine.) The nippers B are eachcomposed of two jaws, bb, the jaw I) being formed on the end of lever b, which is pinned to thecrosshead I). The other jaw, b, is on the end of lever b, which ispinned to lever b by the fulcrum-pin b and connected by link I) tocross-head U. The cross-head b is fast to sleeve 1)", and cross head Ifis fast to treadle-rod b, which passes down through sleeve 1) and isconnected to a treadle-lever,

The blank is laid across the former A and its ends inserted between thejaws b b. The cross-head I) is then drawn away from former A bytreadlerod b and its treadle in this form of my machine, the firstmotion of cross-head b acting to move the levers b, and thereby nip theends of the blank between the jaws b b. The continued movement of thecrosshead b carries with it cross-head b and its connections, as will beplain without detailed description, and this movement of the nippers Bpast the former A strains and stretches the blank until it is forced toclosely fit the former A. In making counters or heel-stiffeners ofleather the operator will then shape the heel-seat by hammering thatportion of the blank which forms the heel-seat close down upon the soleof the formerA While the. blank is held strained. The heel-plate A isthen applied and clamped in place by the Serial No. 208,838. (No model.)

cam-lever A The cross head I) is then re leased, when it is thrown up byits spring I) far enough to cause jaws b to move away from jaws b andrelease the blank, when former A, with the blank securely held upon itby the heel-plate A and cam-lever A, may be removed and set aside untilthe blank has become set. The operator then puts in place another formerand repeats the operation above described on another blank, firstreleasing cross-head If from the catch 1)", and thereby allowing thecross-head b and the parts carried by it to move under the stress of thespring I). It will be found of considerable advantage to elongate thepins b and guide their ends by the slots in plate d, as that not onlykeeps the jaws b 1) wide open, but also carries the nippers away fromthe former and l -b b and moving the nippers B in relation to the formerA may obviously be largely modified, or the former A may be movedbetween the nippers, all these matters being mere matters ofconstruction. f regulate the extent of motion of the treadlerod 1).

The male 'mold or former A is shown as a casting mounted on a stem, butmay be an ordinary last suitably clamped.

What I claim as my invention is 1. In a molding'machine, the combinationofthe male moldor former A with the nippers B, arranged and opeartingsubstantially as described.

2. In combination, the male mold or former A, the nippers B, and theplate A, and means, substantially such as are described, for clampingthe plate against the male mold, arranged and operating substantially asdescribed.
